HIGH PRESSURE PILOT OPERATED CHECK VALVE

Overview

Description

The HDCV is a double pilot operated, hydraulic check valve for use in blocking or load holding circuits

Operation

The valve allows flow from "v" ports to "c" ports, while normally blocking flow in the opposite direction. Flow will be allowed from "c" to "v" when pressure is applied to the opposite side "v" port. The valve has 2.3:1 pilot ratio, so at least 43% of the load pressure held at either "c" port is required at the opposite "v" port to open the flow passage

note: 1.7 bar 1.25 psi minimum allowable check valve spring value for seal code U

note: 4.1 bar 60 psi minimum allowable check valve spring value for seal code us

Features

  • High pressure operation.
  • Check section serviceable as a cartridge.
  • Hardened seat for long life and low leakage.
  • Optional sealed piston.
  • Optional spring ranges.
  • Low pressure drop.
  • All HyPerformance™ products are tested to NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99%.
